Letters Patent No. 109,790, dated November 29. 1870.

IMPROVEMENT IN MECHANICAL MOVEMENTS.

The Schedule referred to in these Letters Patent and making part of thesame.

Nature and Objects of the Invention.

This invention relates to an improvement in machinery, one form of whichis described in my patent 'No.1()8,5-i7, granted October 18, 1870, inwhich I have described a plurality of annular weights retained ineccentric positions by a system of cranks and 1evers, and employed toiinparta continuous and uniform rotary movement to a gear-wheel, fromwhich the power is transmitted to any machinery to be driven.

My present improvement illustrates how a single eccentric annular weightmay be made to produce the effect by the aid of a holder or motoroperating on the lovers in such a constant; manner that one lever willno caught before the preceding one is released, whereby the annularweight is retained in its eccentric position.

Description of the Accompanying Drawing. The drawing represents mydevice in perspective.

General Description.

The standard A, bed 13, and stud-shaft C may bc' J, are rigidly attachedlevers I, which may be arranged in horizontal, vertical, or obliquepositions, according to the angles at which they are attached to thecranks.

In this position they are held by driving-arms \V, arranged in anydesirable number with friction-roilers ii, to take over the successivelevers as the driving'wheel or arms .V are revolved.

An endless belt with suitable catching devices may be substituted forthe wheel W, if preferred, or some other equivalent may be devised ofholding the levers I at the proper angle, and imparting motion to them.

h represents a toothed rim upon the periphery of the annular weight H,through the medium of which the motion may be communicated to anymachinery that is to be driven, or to a governor by which the motion iscontrolled.

The pressure applied to the successive levers causes the cranks G tobear the annular weight H in an elevated or eccentric position, so thatits gravity will act on the cranks in a manner to make their motion uniform, without any disposition to stop on a dead-center.

The power may be transmitted from the annular weight H, or from eitherwheel E or E, through the medium of either belt or gear-in Claim.

I claim as my invention- Au annular weight, H, controlled byholdingdevice \V of suitable construction, through the medium of one or morelevers, I, and two or more cranks, G, substantially as set forth.
